【中文摘要】 采用修正的瓊脂玻皿法研究了四種殺蟲(chóng)殺螨劑對(duì)草菇菌絲生長(zhǎng)的影響.結(jié)果表明,不同藥劑對(duì)草菇菌絲生長(zhǎng)的影響程度存在著顯著差異.其中敵敵畏對(duì)草菇菌絲生長(zhǎng)的影響最大,其平均抑制率為-65.55%;中西溴氟菊酯影響最小,平均抑制率為-11.40%,且在25.00×10-6和20.00×10-6的低濃度下對(duì)草菇菌絲的生長(zhǎng)還有促進(jìn)作用,促進(jìn)率分別為+11.25%和+17.75%;滅螨靈和氯氰菊酯的平均抑制率分別為-29.20%和-29.60%.藥劑的濃度與草菇菌絲的生長(zhǎng)率成顯著或極顯著的負(fù)相關(guān),即草菇菌絲的生長(zhǎng)率隨藥劑處理濃度的增大而降低.本研究結(jié)果還表明,藥劑對(duì)草菇菌絲生長(zhǎng)的影響不僅表現(xiàn)在生長(zhǎng)率上,還表現(xiàn)在草菇菌絲密度、分枝次數(shù)、厚垣孢子數(shù)量及菌絲色澤上.

【英文摘要】 Modified agar culture-dish method was used to study the effect of several insecticide-acaricide on the growth of Volvariella volvacea hyphae. The results showed that the effect degrees of different kinds of agricultural chemicals on the growth of Volvariella volvacea hyphae differed significantly. It was proved that dichlorvos (DDV) had the strongest effect, its average inhibitory rate was ?5.55 %; and bromofluthrinate had the least effect with an average inhibitory rate of ?11.40% and a promotion function on the growth of Volvarella volvacea hyphae under low concentrations of 25.00?04 and 20.00?04 with the promotion rates being +11.25 % and +17.75 % resp., and that the average inhibitory rates of fenproximate and cypermethrim were - 29.20 % and ?29.60% respectively. The concentration of pesticides was significantly, most-signif-icantly or negatively correlated with the growth rate of Volvariella volvacea hyphae. The results also showed that the effect of agricultural chemicals o...更多n the growth of Volvariella volvacea hyphae was not only expressed in the growth rate of hyphae, but also in the density, the branches, the pure white degree of hyphae and in the quantities of chlamydospore.  還原
